This paper presents a low-cost beam-switching antenna array for Ultra High Frequency (UHF) RFID, which significantly lowers the number of blind spots. The array makes use of orientation diversity and spatial diversity to overcome the fading. A unique low-cost and low-lost feeding network is designed to avoid any usage of phase shifters or power dividers, making the design economically efficient. Numerical optimizations and experimental demonstrations are performed to investigate the performances of the proposed antenna array and good agreements are obtained. The tag detection rate is compared with and without beam switching, and a significant improvement in detection rate is observed.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133341750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given that the human head is inside the radio channel, this presents us with a major challenge, both in terms of efficiency and component geometry. This study provides an inductive communication platform for e2e including the selection of convincing topologies for antenna, transmitter, receiver and amplifier circuits. The test setup reaches 100 kBit/s at a distance of 20 cm. The power consumption amounts to 0.8 mA for transmission and 1.7 mA for reception. To achieve the gain needed for such a large distance, a receiver with a 4-stage amplifier is shown, which reaches 45 dB gain.

In this work we present the system level design approach of an FMCW radar system for the detection of breast cancer operating from 14 to 27 GHz with a depth resolution of less than 5 mm. To do this, we simulated a complete setup with transmitting and receiving antenna, skin, fat and tumorous tissues using a 3D electromagnetic solver. Based on these results, we performed a systematic full level modelling to obtain the resulting intermediate frequencies for different tumor depths. The link between system modelling and 3D simulation is possible because the total simulation volume is very small compared to typical radar applications. The workflow is shown schematically in Fig. 1. This approach can of course also be transferred to other comparable applications. The obtained results show that an FMCW radar system is able to detect tumors in breast tissue with a high fat content and to distinguish between different depths. Based on our approach, we also show a possibility for 3D imaging of female breasts.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124382300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The digital dc tuning function embedded in radar ensures less linear distortion with simple hardware implementation. Then, clinical experiments and evaluations are carried out in the operation theatre. Experimental results show that the DCG obtained in this work is aligned well with ECG waveform.
